Abstract
In the general theoretical frame of Biot's model (1956a, b, 1957, 1962 ), the reflection and refraction energy coefficients are studied for a fluid/porous solid interface. The model also includes anisotropy. The analytical expressions of the model enable one to retrieve those of t he isotropic limit case that were published by Wu (1990). The proposed model is numerically validated by comparing our predictions with thos e of Wu (1990).
